4:12 He is the father of circumcision to those who not only are of the circumcision, but who also walk in the steps of that faith of our father Abraham, which he had in uncircumcision.

By faith only he and his seed received the promise.

4:13 For the promise to Abraham and to his seed that he should be heir of the world wasn’t through the law, but through the righteousness of faith.

4:14 For if those who are of the law are heirs, faith is made void, and the promise is made of no effect.

4:15 For the law works wrath, for where there is no law, neither is there disobedience.

Abraham is the father of all that believe.

4:16 For this cause it is of faith, that it may be according to grace, to the end that the promise may be sure to all the seed, not to that only which is of the law, but to that also which is of the faith of Abraham, who is the father of us all.
